Stability tested by running several CAD and Finite
Element programs which depend on memory swapping as much
as on the actual computations. I can live with 3.3 Ghz
and obtaining 3.6 is more of a learning process.

Re: Goosing the Gigabyte ep45-DS3L

D, Thanks for the response.

The good news: The result from trying the maximum values of the settings is that the system will post nicely and start win xp .: runs at 3600 MHz at 42C ( coretemp) . All the settings you suggested were apparently necessary.The maximum values did seem to be necessary as well .

But memtest is really unhappy - gives a 'pair is bad' result right off.
I have not pulled any out yet - wait for your response. I may have fried a pair but all 8Gig show up on cpuz and post. Finite element programs crash. This is the first concern. I can walk the maximum values down later.

Re: Goosing the Gigabyte ep45-DS3L

from Cerulean... I brought the system back to the 9x370 settings with the exception of CPU termination set to 1.44 volts. Xp64 opens, MemTest runs without errors. So the sticks are apparently good. Other timing settings are making the DRAM look bad.

Re: Goosing the Gigabyte ep45-DS3L

Ya, I was about to say you may need 2.1V on the ram to run 2.00B multi. Since you are now at different settings are you happy? If not please post what you have stable, and what you would like to get stable and I will see if I can help

And yes, you can slowly work the timings down one by one testing as you go, start with static tRead, maybe you can get 7-8 to work

Re: Goosing the Gigabyte ep45-DS3L

The above settings are stable in the sense that the rig posts and xinxp64 opens with no reboots. Everything seems well until MemTest - or any other program - is run. 2.1v for the Dram did not help. The very first listing in this thread is MemTest friendly. ( 9x370)
